Abstract:
A base station apparatus of mobile communication system is provided, including an antenna system including first antenna for transceiving signals for a first path among MIMO paths, and a second antenna for transceiving signals for a second path among the MIMO paths, a first duplexer including transmission filter for processing the transmitted signal of first path and reception filter for processing the received signal of second path, a second duplexer including reception filter for processing the received signal of first path and transmission filter for processing the transmitted signal of second path, and a path change unit for providing the transmitted signal provided from the first duplexer to the first antenna and the received signal provided from the first antenna to the second duplexer and to provide the transmitted signal from the second duplexer to the second antenna and the received signal from the second antenna to the first duplexer.
